The high efficiency solar PV module adopts the world's highest efficiency cell with efficiency up to 20%, and efficiency of the module is 25-30% higher than the traditional ones, this cell’s positive pole and the negative pole are on the same side, the cell’s front side can absorb maximum sunlight, so that it can get the maximum power. As for these advantages,high efficiency solar PV module is widely used in Roof Power Generation System、Solar Road Light System、Solar Pumping System、Off-grid/Grid-tie Generation System etc. Different power and voltage of 20% high efficiency solar PV module can also be produced by cutting pieces to achieve.
